Introduce device tree support for the Interface Plus [IFP] Mezzanine
expansion card used with the Qualcomm Monaco Evaluation Kit (EVK).
The Monaco IFP Mezzanine is an additional add-on card which can be
stacked on top of monaco-evk board to extend peripheral capabilities of
monaco-evk used for industrial applications.
It connects via expansion headers on the monaco-evk and provides
following peripherals :
- 4x Type A USB ports in host mode.
- TC9563 PCIe switch, which has following three downstream ports (DSP) :
- 1st DSP is routed to M.2 E-key connector, intended for WLAN endpoints.
- 2nd DSP is routed to M.2 B-key connector, intended for cellular modems.
- 3rd DSP with support for Dual Ethernet ports.
- EEPROM.
- LVDS Display.
- 2*mini DP.
